摘要

采用荧光粉转换的方法制备了纯绿色LED

所制备的纯绿光LED的发光峰值在520nm

其半峰宽约为30nm

法向光强为600mcd。

Abstract

Violet light-emitting diodes chip (GaN-based) was used as primary light source and BaMg

:Eu

phosphors was used as light conversion materials.The EL spectral peak of violet LED chip is 395nm.The exciting spectra peak of BaMg

:Eu

phosphors is at 340nm

but the exciting intensity at 388nm is about the 58% of the maxmum exciting intensity at 340nm (peak).The PL spectrum peak of the BaMg

:Eu

phosphors is at 520nm and the FWHM is about 30nm.The PL spectra of BaMg

:Eu

phosphors is similar with that of green LED.The pure green light emitting diodes was fabricated by the way of phosphors conversion.The EL spectra peak of green LED is at 520 and the FWHM is about 30nm.The luminescent intensity is about 600mcd.
